Currency format for locale de_CH

Question

Hello,
One of my customers has told me that
"Here in Switzerland, currency amounts with 0 cents are written with a long dash, 4.-- instead of 4.00."
It seems that Java doesn't know it. If I'm using the de_CH locale, I will always get 4.00. How can I achieve this with Java besides replacing .00 with .--? Could this be a bug?
Here's a small test. The result is
SFr. 1'234.00
but the right result should be
SFr. 1'234.--
private static void test() {
     Locale locale = new Locale("de", "CH");
     NumberFormat format = DecimalFormat.getCurrencyInstance(locale);
     Currency currency = Currency.getInstance("CHF");
     format.setCurrency(currency);
     BigDecimal amount = new BigDecimal("1234.0");
     String value = format.format(amount.doubleValue());
     System.out.println(value);
}Thank you for your time,
Nicu

Thank you all for taking the time to answer.
I did a quick check on a large Swiss company page (the Swiss Post) and here's what they say:
"Withdraw cash at the post office counter free of charge up to CHF 4'000.- per withdrawal."
They use the same convention. A dash instead of zero. Here's the link: http://www.postfinance.ch/pf/content/en/seg/priv/pay/card/pcd.na_priv.html.
Here's another link that explains the same thing: http://elearning-uk.myswitzerland.com/index.php?SN=pv5qudaru57ilcsdvbftcm7cs1&ac=user_seminar_view&cid=60&pid=255.
Unfortunately, I don't know how I could specify such a format in Java. The only solution I came up with was to replace zeros with a dash if the locale is de_CH. But that's not quite elegant.
